While the big-ticket items sold at Barrett-Jackson in Scottsdale usually hit the block on Saturday, Friday often brings with it a few interesting finds. This year was no different. With an assortment of vehicles ranging from an original 1969 Chevrolet Camaro COPO with a 427-cubic-inch V8 and four-speed manual transmission to a 1929 Ford AA Custom Popcorn truck, you never can tell what's going to show up at Barrett-Jackson.
